OBD2-interfaced Digital Display

This is a discussion on OBD2-interfaced Digital Display within Modifications & Accessories, part of the Under the Hood category; I am thinking of a dashboard gadget which would give us real time information on the following TDI engine parameters ...

Instead of installing additional sensors OR connecting available sensors individually; it would be simple if the gadget could connect (wired or BT) to OBD2 port of the car, to acquire information from the CPU.

This information would help us enthusiasts to know what is actually happening inside the engine and would be of great advantage in a remapped car.

I found this as I was browsing through the web: Banks iQ for 2009-2014 VW & Audi 2.0L & 3.0L TDI 61201

There is one more solution for android based smartphone users: If a BT-OBD2 adapter is purchased online, an application called "Torque" is available for download from play-store, for a fee. There are mixed reviews on this and I am not sure if it works.

I am aware of the VCDS option. But that would be cumbersome to leave it connected all the time. Or is it?

I wanted to know if any of our forum members are already using any of these gadgets OR better still; If anybody is aware of a easier / affordable / solution.

However, in that thread, someone has pointed out that the ELM327 adapter did not work on Skoda Fabia. That makes me wonder if the VW group uses a proprietary protocol or is there something else going on with Skoda. In general, all cars in India made after 2010 support OBDII protocol, and VW should support that too. But I am not yet 100% sure about this given the one Skoda experience that I read.
